Mott, Rock Falls, 111., assignor to International Harvester Compa acorporation of New Jersey Application November 18, 1937,- Serial No.175,203 6 Claims. (Cl. sszs) This invention relates to a device forcoupling a mower attachment to a tractor.

In the patent to Crumb et al.,,1,9l 7,429 of October '16. 1934, there isshown a tractor of the low-axle type, supporting a mower from its axle.It has been found desirable to support this same mower attachment fromthe axle of a high-axle type tractor. In order that for supportingthemower attachment from the axleis necessary. p The'principal; 'objectgoi'this invention .is to provide a. device-"for supporting a mower attach.-mentjfrom thefaxle of a high-axle type tractor.

Another object of the invention is to provide means for supporting amower attachment i'rom the axle of ahigh-axle type tractor in such a waythat the mower attachment may be quickly attached and detached.

29 A further object-of the invention is to provide a device of specialdesign for the supporting of a mower attachment from the axle of atractor. Another object is the provision of means allowing quickattachment and detachment of a mower attachment'in supporting relationto a tractor. A further object of the invention is toprovide a means forsupporting an implement attachment from the axle of a tractor.

30 Another object of the invention is the provision of a device forsupporting. an implement attachment from the axle of a tractor in such away that it may be quickly attached and detached.

35 A further object of the invention is to provide a device of specialdesign, for supporting an attachment from avehicle.

Another object is to provide a device for supporting an attachment froma vehicle in'quickdetachable and quick-attachable relation.

A further object is to provide means for ad- 'justably' and detachablyclamping the aforesaid supporting device to; theaxle of the vehiclev ortractor. a Other objects of the invention will appear'as the disclosureis more fully made.

According to the present invention, the mower attachment is supportedfrom the rear' axle of a, tractorvby means of a pair ofspecial-brackets, which are clamped in adjustable and detachablerelation to the rear face of the rear axle and'extend below the point ofclamping and carry swingable boltsfor supporting the mower atrtachmentin quick-detachable relation. According to one form of theinvention the brackets are attachment this may be accomplished, a changein the'device j projections or ribs l6 clamped to the axle in guidewayswhich are integral with the axle. According to a second form, separateplates providing guideways for the brackets are clamped to the axle.

Figure 2 is a plan view of the tractor andmower attachment;

Figure 3. is a detail, showing on an enlarged scale themanner by whichthe novel bracket for supporting the mower attachment is attached to therear axle of the tractor;

Figure 4 is a sectional view taken along the line 4-4 of Figure 3;

Figure 5 is a detail, showing on an enlarged scale a modified scheme forattaching the bracket to the axle; and, Figure 6 is a sectional viewtaken along-the line 6-6 of Figure 5. As seen in Figures 1 and 2, atractor III has an engine frame ll supported on a front steering truck(not shown). The rear end is supported on an axle housing II, which isin turn supported by traction wheels I 3. The axle housing is well abovethe center of the traction wheels, driving connection'between the axleand the wheels being established through gears contained in the housingsH. The tractor is known as the high-axle type. v Supported rearwardlyfrom the axle housing is a mower attachment ii of the type shown andclaimed in the patent toCrumb et a1. 1,977,429, October 16, 1934. Nodescription will be made of this attachment, since it is fully describedin the aforementioned patent and forms' no part of ,the presentinvention, other than to state that it must be carriedat a certaindefinite height above the ground. As shown in the patent to Crumb etal., the mower attachment is supported by a low-axle type tractor; thatis, a tractor which has its'axle in line with the centers of the wheels.In order that the mower attachment might be supported at thesame heightabove the ground from a high-axle type tractor.

itwas necessary to devise a new supporting means. This will now bedescribed. The axle housing has, on each side oi its central portion,guideways in the form of integral which extend outwardly from the rearface of the housing andthen toward one another. The novel bracket memberof this invention consists oi a-flat plate I! con-. stituting a base,,apair of standards I I joined to the plate l'| through foot portions. I8,and a pair 66 -ing.

of swingable bolts mounted between the standards I8 at their oppositeends on pins 2! and carrying nuts 22. Set screws 23 serve to hold thebracket member in place in the guideways. The mower attachment issupported at each side by a second bracket 24 which has a flat portionhaving slots 25 at each end. The swingable bolts 20 fit in the slots andby means of the nuts 22 hold the second bracket against the standardsl8. Since the bolts may slide into or out of the slots quickly andeasily, a quick-attachable connection is formed between the tractor andthe mower attachment.

It is to be noted from Figure 4 that the standards i8 extendconsiderably below the axle housing H. ,The upper swing bolt is slightlybelow the upper side of the axle, and the lower swing bolt isconsiderably below the lower side. By shaping the standards in this way,applicant has made it possible to support the mower attach mentoriginally intended to be supported froma low-axle type tractor from ahigh-axle type tractor.

The bases of the novel brackets are supported in guideways on the axlehousing which extend transversely of the tractor.

tor may be adjusted. The brackets may be quickly detached from themachine by displacement beyond the guideways.

Figures 5 and 6 show a modified construction wherein the guideways' arenot integral with the axle housing but are formed as inturned edges 21on a plate member 25. This member is clamped to the axle housing bymeans of pieces 21 and studs 28, welded or otherwise secured as at 29 toplate member 26 and pieces 21', clamp members 30, bar 3|, and nuts 32.The plate member has alateral extension 33 by means oi which it may bebolted, as at 34, to the edge of the opening in the central part of theaxle hous- The novel bracket member is, attached in the guideways in thesame manner as in the constructionshown in Figures 3 and 4. It maysimilarly be adjusted along the length of the guideways for the sake ofadjustment of the mower attachment laterally of the tractor and may beremoved by displacement beyond the guideways.

From the foregoing description it will be seen that a novel means hasbeen provided for supporting a mower attachment from a high-axle typetractor. It will be readily appreciated that the novel supporting'meansneed not be limited in its use to a mower attachment and highaxle typetractor, but may be employed for supporting an attachment on a vehiclewherever the point of connection on the attachment must be displaced a.considerable distance either up or down from the point of connection tothe vehicle.

It-is intended to limit the invention only in the scope of the appendedclaims.

What is claimed is:
